fiasKO [112]3 years ago
7 0

Answer:

Step-by-step explanation:

2x² + x -1 = 0

x² + x² + x -1 = 0

(x²  - 1) + x²  + x  =0

(x + 1) (x - 1) + x(x + 1) =0

(x+1) (x - 1 + x) = 0

(x + 1)(2x - 1) = 0

What are the solutions of the equation (2x + 3)^2 + 8(2x + 3) + 11 = 0? Use u substitution and the quadratic formula to solve.
iris [78.8K]
U=2x+3, x=u/2-3/2
u^2+8u+11=0
u1=(-8+sqrt(64-44))/2=-4+sqrt(5)
u2=-4-sqrt(5)
x1=u1/2-3/2=-7/2+sqrt(5)/2
x2=u2-3/2=-7/2-sqrt(5)/2
